As high heat plagued much of California, a Modesto family got a chilly surprise this week when a block of ice soared from the sky and through the roof of their home.

Monica Savath told KOVR-TV that she and her family were sitting in the living room of their home Wednesday when they heard a large crash. She went into her garage and noticed a gaping hole in the roof and the sun shining through it.

On the ground was a block of ice, melting in triple-digit temperatures.

Savath and her neighbors were left wondering where the ice came from.

The FAA says they haven’t received any similar reports. And the National Weather Service says temperatures in the area have been so hot that ice formation is nearly impossible.

Meteorologist Jason Clapp said the ice incident was definitely not weather-related.

People across the country have reported similar incidents in the past, and planes have been suspected. In those instances, ice falls from a plane because of a leak in a tank containing solid waste. The ice usually appears blue because of a chemical added to waste water.

In this case, the ice was not blue.

FAA spokesman Ian Gregor said Savath and her family has not contacted the agency to report the falling ice, but an FAA inspector went to Savath’s home Thursday morning anyway.
